Courteney Cox

It's a wrap for her, in Marc Jacobs

Courteney Cox donned a demure navy-and-black wrap dress by Marc Jacobs for the premiere of Bedtime Stories. In the family-friendly fantasy film, Cox plays the sister of Adam Sandler's character, whom she leaves in charge of her children when forced to travel (the maternal role isn't a huge stretch for the actress, who gave birth to daughter Coco in 2004). In January, Cox will ditch her designer garb for Scrubs: the former Friend joins the sitcom for three episodes to kick off its move to ABC.
